Application inea May 12, 191s. serial No. 97.1.14.

the inner side of, the rail, and a groove 5 is provided on the outer side of the rib, that is, between the rib and Jthe plate 3 for re- -ceivingthe flange and gradually lifting it to the top of the plate.

The plate isprovided at Opposite side edges with depending flanges 5 and 6 of a 1 length to extend to the under surface of the ball or tread of the` rail when the derailer is in place on the rail as shown in Fig. 2. These flanges engage the opposite sides of v'the ball or tread when the derailer is in To @ZZ whom t may concern Be it known that I, WILLIAM P. NEWKIRK, a citizen of the United States, anda resident of Portsmouth, in the county of Scioto and State of Ohio, have invented a new and useful Improvement in Derailing Devices, ofwhich the following is a specification.

My invention is an improvement in derailing devices,V and has for its object t0` provide a device of the character specified intended for the use of inspectors, repairmen, and the like, and capable of quick attachment to and detachment from the rail, wherein a plate is provided to be seated on the tread of the rail, and having depending flanges at each side edge for engaging opposite sides of the ball or tread of the rail, and having at one end of each flange a downward extension, extending below the under surface of the tread, the said flanges being at opposite sides and opposite ends of the plate and spaced apart from each other a suiiicient distance to permit the derailer to be seated on the rail with the flanges ensaid extensions being of avlength to extend well below the ball or treadas shown. Each extension is provided at its loweredge with ank inturned rib or web -`9 and 10, respectively, of a width to engage the web of the railwhen the derailer is properly seated, and these webs are inclined with respect to the horizontal and .in oppositev directions, .both inclining upwardlvtoward their inner for adjacent ends. The extension 8 is progaging the rail when the plate is transverse gvided at its opposite ends with vertical reto the rail, each extension having `an in-"inforcing ribs 11, the said ribs extending wardly extending rib at its lower end for from the rib or web 9 to the upper surface engaging the web of the rail when the plate of the plate as Shown. is turned into register with the rail, the said A key lOlOCk iS D'IOV-ldd fOI @Mh eXtenribs being inclined upwardly toward theirs, sion, and adapted to be arranged between inner ends, and key blocks fitting between'-'the web orrib and the under surface of the the ribs and theunder surface of the ball ball or tread, and the said blocks 12 and 13 or tread to lock the plate in place. v las shown in Figs. 6 and 7 are wedge-shaped, that is, each block has one edge inclined at In the drawings r-Figure l is a top planv view of' the improved derailing device, Fig. lthe same angle as the inclination of the webs 9 and 10, and the opposite edge is rough- 2 is a Side view looking at one side, Fig. 3 is a similar view looking at the other side, ened yor corrugated as shown and is adapted Fig. 4 is a front view with the rail in section, Fig. 5 is a front view showing the manner of placing the device on the rail, and. Figs. 6 and 7 are perspective views of the key blocks. l The present embodiment of the invention t is shown in connection with a rail 1, the rail being supported by the usual ties 2, and the device comprises a plate o r block 3 of suitable length, having its ends inclined or beveled as shown, and having intermediate its ends an inclined rib 4 for engaging the flange of a wheel to constrain the said flange to pass across the rail to derail the wheel. AS shown more particularly in Fig. 1, this rib 4 extends beyond one side of the plate, that is, beyond that side which will be at the rail. These key blocks 12 and 13 are seated on the webs 1 0 .and 9, respectively, and it will be evident that when the Vdevice is placed on the rail as shown in Fig. 5 and is turned into the position of Fig. 4 and the key blocks are inserted as indicated in Figs. 2, 3 and 4 the derailer will be firmly locked upon the rail against twisting or ,lateral` movement in either direction. Each key block as shown is of I-shape in cross-section, and the block 13 has a longitudinally extending arm 14, formed by a bar which has one end oli'set into contact with the body of the key block at the large end thereof and the bar .extends in parallel spaced relation place, and each flange is provided at one end with an extension 7 and 8, respectively, the

to engage the under surface ofthe tread of l secured thereto as shown, and thebody of with respect to the body of the block. This arm is adapted to engage openings 15 in the reinforcing ribs 11 and the free end of the arm is provided with a series of openings 16 for receiving a pad lock` 17, or the like, to hold the key block in place.

A flexible member 18, as for instance, a chain or the like, is secured to a laterally extending lug 19 on the key block 12 at the large end thereof, and this chain is adapted to engage a hook 2O on the extension 7 at the inner end of the said extension to hold the key block in place, and a coil spring 21 is interposed in the length of the chain. lVhen the spring is placed under tension before a link of the chain is engaged with A the hook 20 the key block will be firmly held against any possibility of jarring loose. A second chain 22 may be used for anchoring the device to the rail against sliding movement longitudinally thereof. This chain has one end connected to the hook 20 and the other is provided with a hook 23, which is adapted to engage the opposite edge of the base flange of the rail when the chain 1s passed downwardly below the rail as shown more particularly in Fig. 4.

A socket 24C is provided intermediate the ends of the plate and near the side adjacent to the flange 5, for receiving the end of a signal staff 25. This staff is provided at its upper end with a signal 26, the said signal in the present instance, being a ring with the legend Safety first and the ring. is provided with a hook 27 at its upper side for engagement by the bail or handle .of a lantern for use at night. A series of indicating plates 28 is pivoted to the upper end of the staff below the ring, and these plates bear legends as for instance Inspectors, Repairmen, Air brakes and Private. Preferably the plates are arranged to be held in the extended position shown in Fig. L by means of thumb screws or the like, or they are dropped into inoperative position in register with the staff.

In use, the device is especially intended as a warning and derailing device to prevent injury to inspectors, repairmen and the like. The device is placed on the track by arranging the plate 3 transversely 0f the rail as shown in Fig. 5, and with the lower edges of the flanges 5 and 6 resting on the ball or tread of the rail and with the extensions 7 and 8, depending on opposite sides of the ball or tread. The device is then turned into parallelism with the rail and the Hanges 5 and 6 drop down on opposite sides of the ball or tread and with the extensions 7 and 8 below the ball or tread and with the webs 9 and 10 in contact with the web of the rail. The key blocks 12 and 13 are then placed, the block 12 being locked by the chain 21 and the block 13 by the pad lock 17. l

The staff 25 with its signals will warn trainmen coming in on the track in use, and if they neglect the warning the train will be derailed, thus absolutely preventing injury to the employees. The plates 28 indicate to all concerned the character of work in progress, and as each employee completes his particular labor he will drop the plate 28 pertaining to such labor.
